Blount’s Disease at DRHC Dubai Pediatric Orthopedic Clinic

Blount’s disease is a rare but serious growth disorder that affects the tibia (shinbone), causing the legs to bow outward. This condition, also known as tibia vara, disrupts the normal development of the growth plate at the top of the tibia, leading to abnormal bone growth and deformities. Unlike the bowing of legs that is normal in young toddlers, Blount’s disease progresses over time and requires medical treatment to prevent worsening complications.

At DRHC Dubai, we offer expert evaluation and treatment for children with Blount’s disease, using advanced diagnostic tools and personalized care plans to promote healthy bone development. Early diagnosis is critical to managing the disorder effectively, so parents are encouraged to consult a specialist if they notice persistent bowing in their child’s legs.

Causes and Risk Factors

While the exact cause of Blount’s disease remains unknown, several contributing factors have been identified:

  • Early Weight-Bearing Activities: Infants who start standing or walking before 12 months may place excessive pressure on their tibial growth plates.
  • Obesity: Increased weight puts more strain on the developing bones, contributing to the progression of the disease.
  • Family History: Genetic predisposition may play a role, with a higher incidence seen in families with a history of the disorder.
  • Ethnicity: Studies show that Blount’s disease is more common in children of African descent, though children from all backgrounds can be affected.
  • Postural Stress and Alignment Issues: Mechanical stress from abnormal walking patterns or intoeing (feet turning inward) can contribute to the development of the disorder.

Types of Blount's Diseases

Blount’s disease is classified into two main types, based on the age of onset:

1. Infantile Blount’s Disease

  • Age Group: Occurs in children younger than 4 years.
  • Characteristics: Typically affects both legs (bilateral) and can be mistaken for normal toddler bowing.
  • Progression: If left untreated, the bowing becomes more severe with growth.

2. Adolescent Blount’s Disease

  • Age Group: Develops after 10 years of age.
  • Characteristics: More likely to affect one leg (unilateral) and is commonly associated with obesity.
  • Severity: Progresses rapidly during growth spurts, leading to significant leg deformity if untreated.

Signs and Symptoms

The hallmark symptom of Blount’s disease is progressive bowing of the legs, where the knees curve outward while the ankles remain close together. However, there are other signs that may indicate Blount’s disease:

  • Intoeing (Feet Turning Inward): A noticeable inward rotation of the feet when walking.
  • Uneven Leg Length: One leg may appear shorter than the other.
  • Knee Pain or Stiffness: As the condition progresses, children may complain of discomfort in the knees.
  • Waddling or Altered Gait: The child may develop a limp or have difficulty walking.
  • Joint Pain: In severe cases, the abnormal alignment can lead to early onset of joint pain, especially in the knees and hips.

Complications of Untreated Blount’s Disease

If left untreated, Blount’s disease can lead to significant complications, including:

  • Permanent Leg Deformities: Severe bowing can persist into adulthood.
  • Early-Onset Arthritis: The misalignment places stress on the joints, increasing the risk of arthritis in the knees or hips.
  • Walking Difficulties: Altered gait patterns can cause discomfort and mobility issues.
  • Chronic Pain: Joint stress from misalignment may lead to long-term pain and stiffness.

Diagnosis

At DRHC Dubai, our pediatric specialists conduct a thorough evaluation to confirm the presence of Blount's disease. The diagnostic process may include:

  • Clinical Examination: A detailed physical exam to assess the degree of bowing, leg length discrepancies, and walking patterns.
  • X-rays: X-ray images help visualize bone alignment and identify irregularities in the growth plates.
  • MRI or CT Scans: In some cases, advanced imaging is required to assess the extent of damage to the growth plate.
  • Gait Analysis: Used to monitor walking abnormalities that may affect treatment decisions.

Treatment Options

Treatment for Blount’s disease varies based on the child’s age and the severity of the condition. Early intervention offers the best outcomes and may prevent the need for surgery.

  1. Bracing (for Infantile Blount’s Disease): Bracing can help realign the legs in younger children by guiding the growth of the tibia. Braces are most effective when used in children under 3 years old with mild to moderate deformity.
  2. Physical Therapy: Physical therapy can improve the child’s gait and strengthen leg muscles. It is often used as a complementary treatment alongside bracing or surgery.
  3. Surgical Options (for Severe or Progressive Cases)
    In advanced stages, surgery may be required to correct the deformity. Common procedures include:
    • Tibial Osteotomy: The bone is cut and repositioned to correct the alignment.
    • Guided Growth Surgery: Metal plates are placed temporarily to control bone growth in the desired direction.
    • External Fixation Devices: A specialized frame is used to gradually straighten the bone over time.
    • Epiphysiodesis: A growth-modifying surgery performed to correct leg length discrepancies.

Post-Treatment Care

After treatment, children require regular follow-ups to monitor their progress and ensure proper healing. Our specialists at DRHC Dubai provide comprehensive post-treatment care, including:

  • X-ray Monitoring: To track bone growth and alignment.
  • Physical Rehabilitation: Strengthening exercises to restore normal walking patterns.
  • Nutritional Counseling: For children with obesity, weight management is essential to prevent recurrence.
